    $\begingroup$ What if you plug the black and white image into the last mix node factor? $\endgroup$ Feb 7 '19 at 21:09

    $\begingroup$ ah! Thanks, yeah, non need for the extra mix nodes. Just using the image for the factor did it. I tried using it the alpha of that as a factor initially. Thanks again! $\endgroup$

  • $\begingroup$ I like Uncle Snail's suggestion. I am interested in screenshot of solution, if it is possible with you. For study purpose only, I am collecting photos of node compositing for scrapbooks as in link here. Credits are given. docs.google.com/presentation/d/… $\endgroup$ Feb 8 '19 at 3:03

Here you go - I plug the black and white image into the mix factor of the mix shader as a way to define where the transparency shader will take effect. enter image description here
